Compact Tuning Fork Liquid Level Switches Used at Nuclear Power Plant - 1

Compact Tuning Fork Liquid Level Switches Used at Nuclear Power Plant Recently, Jiwei Ring-21 Compact Liquid Level Switches have successfully replaced photoelectric level switches for liquid level measurement in the water vapor sampling and analysis system, as well as circulating water system of the conventional island at Fuqing nuclear power plant. High requirements for instruments Nuclear power plants have strict requirements on stability and reliability of instrumental devices. In addition to compact and convenient for installation in a narrow space, the following conditions should be met in terms of reliability: 1. Certificates and test reports on seismic resistance, durability and electromagnetic compatibility. 2. With LED alarm and indicator. 3. Not affected by bubbles or foams. 4. With self-inspection function. Advantage of Ring-21 compact tuning fork liquid level switch Ring-21 Compact Liquid Level Switch is based on fork resonant principle. When fork body which vibrates in harmonic resonance immerses into the measured liquid, vibrating frequency of tuning fork will greatly decrease, so does the output of piezoelectric detection device.
